EXTENSION-CORNICE.

SPECIFICATION forming part of Letters Patent No. 265,851, dated October 10, 1882.

Application tiled May 9, 188:2.

To all whom it may concern:

Be it known that I, JAMES M. MONTGOM- ERY, Jr.. of Columbus, in the county ot' Franklin and State of Ohio, have invented certain new and useful Improvements in Extension- -Oor-nices'; and I do hereby declare that the in Fig. 1. Fig. 4 is a perspective View of one ot' the bracket-plates detached; and Fig. 5 is a similar view, showing a moditied construction of the same.

Similar letters of reference indicate corresponding parts in all the ligures.

My invention contemplates certain improvements upon the adjustable or extensible cornice for which Letters Patent ot' the' United States No. 241,400 were granted to me on the 10th day of May,'l881; and it consists in the bent or bulged bridge-plates which span and brace the cornice and the extensible arms, and form boxes for the sheaves or pulley s over which' the operating-cords run, as hereinafter more fully described and claimed.

ln the accompanyingdrawings, the letterA represents thecenterpieceof the cornice, which may be suitably ornamented.

B B are the extensible arms or wings, which are provided with the usual end pieces, B B'.

To theupper and lower sides of the center piece are. secured grooved strips a a., forming ways for the extensible arms B, whichare provided with studs or projections b b, h'tting into the grooved ways. bridge-pieces O, which connect the top and bottom strips, a nat opposite ends of the center piece, A. These bridge'pieces are made of metal or other suitable material, and may be slotted, as shown at'- c, to make them of as light weight as possible consistent with the requisite degree ot' strength. At each end is a screw-hole, 1,'or the insertion of screws, by which they are fastened to the strips a a; and c is a bulged or raised part, within which is a pin or stud, f, which forms a spindle for the Arms B are spanned by (No model.)

roller D. If desired, however, this roller may be dispensed with, in which case the part e is u made with a half-round shoulder, D', as shown in Fig.5of the drawings. The rollers or guides may beplaced in the center of bridge-plate O, as shown in Figs. l and 3, or at the upper part ot' it, as shown at the detail views, Figs. 4 and 5 of the drawings, as desired.

E is an endless cord or belt, which may be of hemp, leather, wire, or other suitable material, passing around the pulleys D D or stationary shoulders D D', as the case may be. Said cord is secured nearits middle part to the inner or meeting ends of the extensible arms B B by tacks or other suitable fastenings, g g.

From the foregoing description, taken'in connection with the drawings, the operation of this device will readily be understood. `The arms or wings B B, sliding in the recessed center piece, A, between the ways a a, may be extended to both sides thereof to conform to the width ofthe door or window over which the cornice is to be placed. The said wings being connected by the endless cord E in the manner described, it follows that both sides willbe extended evenly and simultaneously, so that the center piece, A, will always remain exactly in the middle.

The bridge-plates O C, by connecting the ways a a, at opposite ends of the center piece, strengthen the entire structure and form additional ways or guides for theV extensible ends B B.

Having thus described my invention, I claim and desire to secure by Letters Patent ot' the United States- In an extensible cornice of the described class, the bridge-plates O C, spanning and bracing the body of the cornice and its extensible arms, and bent or bulged to form boxes e, having pins or studsf, in combination with the sheaves or pulleys l) and cords for exteuding the arms, substantially as and for the purpose shown and specified. f

ln testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
